Groucho: "I had one line which was 'Let's get something that we can all enjoy.' The idea was that Betty Grable and Harry James were sitting in the front seat of a DeSoto and I was hiding in the back, on the floor. Thus when Betty Grable pressed the radio dial again, tuning to my show...the producer asked me to eliminate the line...the big surprise was supposed to be me bouncing into the scene...it occurred to me that in Cocoanuts and Animal Crackers I had about 90 sides of dialog. Here I had only one line and they even clipped that. Well, I guess that's show business." -- The Groucho Letters, 1967. The scene he describes appears in "Shower of Stars" of Jan 18, 1955

18 Jan 1955 - Shower Of Stars
CBS, 60 min
Betty Grable, Harry James, and Ed Wynn, and about a half-dozen guests who made cameos, including Groucho.The show bordered on being an infomercial for Chrysler products. Groucho's appearance was VERY brief! In one scene, Grable and James are taking a new car out for a test drive, and they turn on the radio just in time to hear the opening of a YBYL broadcast. Just as George Fenneman says "The One.. The Only.. Groucho!" Groucho pops up from the back seat and says something like "Hey! That's Me!"

Uncle Miltie asks if Harpo could get him one and didn't exactly have in mind the Coke bottle Harpo brought back. Along with this echo of past mime scenes, Harpo gives his leg to his host, plays around hungrily during a "Kraft" recipe commercial, and makes faces through his harp that had a studio audience roaring while Berle was on camera." -- The Marx Bros.: Their World of Comedy, 1966.

Apr 1959 -
British TV"Chico appeared on a British variety show some time after THE INCREDIBLE JEWEL ROBBERY. I believe this was when he landed in England in 1959, only to experience severe stomach pains, forcing him to cancel a proposed tour just two days after he arrived. Chico looks terrible in the bit (using Harpo's Coke bottle gag for the announcer) but plays "Listen to the Mockingbird" (as in GO WEST) with the old flair. Can't set the date on this, but the opening frames of the show feature photos of Chico in the policeman's outfit that he wore in INCREDIBLE JEWEL ROBBERY. The above footage is excerpted in the Disney Channel bio on the Marxes aired several years ago." (Edward D. Watz)
